Mk 6 Fiesta 1.6 TDCI - Limp Mode?

[dhutch]

We have a 58plate 90hp 1.6 diesel fiesta which has recent started occasionally suffering from reduced power.

- Struggles to accelerate at all above 60-70mph
- Will not rev above 3.5k rpm while being driven, or 4k under no load.

Typically key cycling it will clear the issue.

No warning lights at all, have not got a OBD reader.

Boost control actuator, control solenoid, sooted vanes, turbo underboost, split hoses, DPF wiring issues, etc have all be mentioned in past threads on here and FO Club forums.

Anything to look for other than getting a OBD reader on it?

As an update, diagnosis was very low boost and a failed turbo.

£900 later, it's still doing it, apparently the boost is a bit low, might just be able to adjust waste gate but speaking with parts outlet before hand to ensure no issues.

Booked in for a replacement turbo on Wednesday warranty replacement from the parts supplier.
